1300 to 1600

I?m thinking on upgrade my 1300 DP to a 1600 DP for 20 years...at least. The engine was rebuilt 12 years ago and since I made about 10 000KM (6250 miles). At the time I putted used pistons and cylinders because of the money, so I don?t need to rebuild the engine only take of the cooling surround, the heads and pistons. I never pull out the engine so I also don?t know if I will try to do it myself. I will ask the price to a guy, whish his job is beetle engines rebuilding to know if I will save any money. My questions are the following:

1- Do I only have to buy new cylinders pistons and heads and valves? Can I use the some rocker shafts and springs for example? 2- Want tools do I need? (this is my first concern) 3- I want to keep my stock Carb Solex 31 pic to keep the stock looking 4- Can we feel a hard difference between a 1300 and a 1600?

Thanks in advance Joao

Thanks for the reply

I know, that you know how machine them, but I don't know if I can find any one with the information to do that. I have to think about that

I think that the best I have to do is:

1- News 1300 dome pistons and cylinders (I have flat ones now) 2- Rebuild the carb 3- Check the valve guides

to have my 44HP back again

The 1300 heads can be machined larger for the 1600 cylinders. If they are otherwise in good shape, then you can keep using them.

Uhh. That's a long list. Nothing too special, basic tools mostly. Depending on what else you want to do.

The 1600 dual port engine came with a bigger diameter intake manifold and 34mm carburator.

I don't think there would be a BIG differnece. Better low end power, but restricted higher rpm performance.

Hi

I just got myself a 68 bay bus at the end of last year. The engine,

1600 (AS), sp was bad (leaking oil - end play ).

I took it out and put a 1300 DP (AB) out or one of my beetles in it.

Up till then my daily driver was a split bus with a 1600 SP (B) engine.

I feel the 1300 DP in the bay has MUCH more bottom end grunt !

Dont know why - It surprised me too !!!

Probly isnt what you wanted to hear :-)

It depends on the rest of the engine and gasoline available. The factory built thousands of 1300 engines with domed pistons. Stock items. Just hard to find.

My engine come stock with dome pistons. I saw them. I think that all AB engines come with those pistons. When a friend of mine opened the engine 12 years ago, they here completely damage. Two rings here broken, but it started always at first time.

1 Litre of oil witch 1000 km. One guy sold me used flat pistons to rebuild the engine. I think that the compression is not the same. I think that I can find dome pistons somewhere. I have here gasoline with 95 and 98 RON so that is not a problem and on the door of the gas cap, it says that it can work with 91 RON.

That is what I'm going to do. Next Saturday I will take my care to make a few repairs and also to put new pistons 1600. The heads will be machined and the valve guides checked. I will put back the thermostat on the cooling system I will get you know the result. On the end of the month it will run as a 1600.
